She's 9 mo now but has done it since she was tiny. I don't mean she wakes up and cries, her face crumples while she's still asleep then she wakes up crying. It's so sad Where/when she sleeps doesn't seem to make a difference - she has just done it while asleep on my lap (usually her favourite place to sleep). Doesn't seem to happen at night though.
Any thoughts on why she does this? Or is it just one of those things?
